Wi-Fi does not work on Xiaomi: all the reasons and how to fix it in 10 minutes

Are you trying to connect to your home network, but Xiaomi stubbornly ignores the password or does not see the access points available at all? Or the connection is constantly interrupted, although everything is stable on the laptop? Wi-Fi problems on Xiaomi smartphones are one of the most common complaints of users, and the reasons can be hidden in both software failures of the MIUI and hardware problems of the communication module. In this article, we will analyze all possible scenarios, from the banal β€œforgot password” to hidden router settings that block the connection of your model Redmi or POCO.

It’s important to understand that if WiFi stopped working after a firmware update, a phone drop, or a router change, the diagnostic algorithms will be different. We won’t offer β€œreboot phone” as a universal solution (although this is really the first step). Instead, you will receive clear, step-by-step instructions tailored to your specific situation, including rare cases like conflict. IP-address-blockage MAC-For convenience, we collected data on Xiaomi models. 11T/12 Pro/13 Lite, Redmi Note 10/12 and POCO F4/X5 β€” There are nuances with the drivers of Qualcomm and Mediatek modules.

Before you rush to the service center, check that the problem can be solved in 2 minutes without losing data, starting with the most obvious β€” but often overlooked.

1. Checking basic settings: what you might have missed

Yes, it sounds trivial, but 30 percent of Xiaomi support calls are closed after checking basic things, and it's not just about the plane's mode on (although it does happen).

  • πŸ”„ Reset the router. Turn it off the power for 30 seconds, it'll drop the cache. DHCP This is especially true for TP-Link and Keenetic routers, where sometimes the session of devices sticks.
  • πŸ“Ά Make sure that the Wi-Fi is on on the phone. MIUI 14+ Quick settings can hide the WiFi icon – swipe down twice from the top edge of the screen to see the full list.

3. Router Conflicts: Why Xiaomi Can't See Network or Don't Connect

Sometimes the problem isn’t with the phone, but with the router settings, especially with newer Xiaomi models that support Wi-Fi 6 (802.11ax), which may conflict with older routers.

  • πŸ”„ Incompatibility of standards, if the router only works 802.11b/g, And your Redmi Note. 12 Pro+ trying to connect 802.11ac, Solution: In the router settings, turn on mode. 802.11n/ac/ax (mixed).
  • πŸ”’ Lock-in MAC-Some routers (especially enterprise routers) only allow certain devices to connect. MAC router administrator panel.
  • πŸ“‘ Hidden net (SSID). If your network does not broadcast the name (hidden) SSID), MIUI You may not see her. SSID router-setting.
  • πŸ”„ Double tuning DHCP. If there are two routers on the network DHCP-server (e.g. main and repeater), this can cause conflicts IP. Turn it off. DHCP secondary.

How to check the settings of the router:

  1. Connect to the router from another device (laptop).
  2. Enter 192.168.0.1 or 192.168.1.1 (the address is indicated on the router sticker).
  3. Go to the Wireless Settings or Wireless Mode section.

If you have a Xiaomi router (Mi Router), update its firmware through the Mi Wi-Fi app. In older versions, there was an error with the authorization of devices on MIUI 13+.

4. MIUI software failures: clean cache and reset settings

MIUI, despite all the updates, sometimes crashes the network modules, and this can be either a complete absence of WiFi or a permanent disconnection.

Cleaning the cache of system applications:

  1. Go to Settings β†’ Applications β†’ Application Management.
  2. Click on the three dots in the top corner and select Show System Processes.
  3. Find WLAN or Wi-Fi Direct, open and click Clear cache.
  4. Repeat for Google Play Settings and Service.

Reset all settings (without data loss):

If cleaning the cache didn’t help, try resetting only the system settings without affecting user data:

  1. Go to Settings β†’ About the phone β†’ Reset settings.
  2. Select Reset all settings (not "Reset to factory"!).
  3. Confirm the action. The phone will reboot.

How to check for hardware malfunction:

  1. Test in the engineering menu: ##4636### Select Wi-Fi information and see Wi-Fi status. If there is a Disabled or error, the module is faulty.
  2. Check through ADB (Adb shell dumpsys wifi Look for lines with driver state and interface name. If it's empty or there's an error, the problem is the hardware".
  3. Connect to another network. Try connecting to a mobile hotspot (from another phone) or a public WiFi. If it doesn't work everywhere, it's the phone's fault.

⚠️ Warning: If WiFi stopped working after replacing the battery or disassembling the phone, there is a 90% probability that the master damaged the antenna plume. 11T Pro and 12S Ultra antenna tracks run through the middle frame, and they are easy to break with careless opening.

If the diagnosis is confirmed, there are two options:

  • πŸ”§ Repair in the service center (replacement of the Wi-Fi module will cost 1.5-3 thousand rubles).
  • πŸ“± Use of the USB/Type-C Wi-Fi adapter (for example, TP-Link) UE300). You need a phone with support for this. OTG root rights (or firmware with a core that supports external adapters).
